"Gas switches" is how many different mixes this computer can be programmed to switch between mid-dive, mostly relevant for technical/staged-decompression diving. It doesn't tell you which gas types (air, nitrox, trimix) are supported. See Gas types and the product description above for that.

Pros
  • Purpose-built freediving algorithm that flags Taravana (decompression-sickness-like) risk
  • Compact 48mm case, wears like an everyday watch
  • User-replaceable CR2450 battery with a sleep mode to save power
Cons
  • Freediving only, no scuba/nitrox dive modes, unlike the visually similar Goa
  • No digital compass
  • No app connectivity without the separate BT Interface accessory
Diver community sentiment
Mostly positive

As a freediving computer, the Nepto is discussed mainly on freediving-specific forums (DeeperBlue.com) rather than scuba-focused ones. There, freedivers generally praise it as strong value, citing a big, high-contrast, easy-to-read dial, a long-lasting user-replaceable battery, solid build quality, and a well-liked graphic log view showing a whole day's dives together. Recurring gripes include buttons some find stiff to press, a battery-replacement process (small screws and an O-ring) seen as fussier than rivals like the Seac Driver, and a companion phone app described as basic.

Summarized from public forum discussion (Scubaboard, Reddit, and similar), not a survey we ran ourselves. See the linked threads for the original conversations.

The Nepto is Cressi’s dedicated freediving computer, sharing its compact watch case with the scuba-oriented Goa but running a different algorithm built around freediving safety, specifically guarding against Taravana and pulmonary edema risk on repeated breath-hold dives. It’s not a substitute for a scuba computer.
